Matrigel coated boyden transwell chambers

Manufactured by BD

Matrigel-coated Boyden transwell chambers are a cell migration and invasion assay used to measure the ability of cells to migrate through a porous membrane. The chambers are coated with Matrigel, a basement membrane extract, to simulate the extracellular matrix. Cells are seeded in the upper chamber, and the migration of cells through the membrane is measured over time.

Matrigel Invasion Assay Protocol

In vitro invasion assay was done using matrigel-coated Boyden transwell chambers from BD Biosciences. Transwells were soaked in 50 µl serum-free medium for 30 minutes at RT and then ~40,000 cells (in RPMI medium containing 0.1% BSA) were placed into the upper chambers. These chambers were then placed in 24 well plate (one per well) on top of 500 µl RPMI medium containing 3% fetal bovine serum as chemo-attractant. Inhibitors were added directly to the medium and mixed. Then the cells were incubated at 37 °C in the CO2 incubator for 16 hours. Non-invaded cells along with matrigel in the upper chambers were scraped with a cotton tipped applicator and then the membranes were fixed in methanol, stained with 0.025% crystal violet, and observed under a Leica microscope at x200.

Matrigel-based Invasion Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
In vitro invasion assay was done using Matrigel-coated Boyden transwell chambers from BD Biosciences. Transwells were soaked in 50-mL serum-free medium for 30 minutes at room temperature and then $40,000 cells (in RPMI medium containing 0.1% BSA) were placed into the upper chambers. These chambers were then placed in 24 well plate (one per well) on top of 500 mL RPMI medium containing 3% FBS as chemoattractant. Inhibitors were added directly to the medium and mixed. Then the cells were incubated at 37 C in the CO 2 incubator for 16 hours. Non-invaded cells along with Matrigel in the upper chambers were scraped with a cotton tipped applicator and then the membranes were fixed in methanol, stained with 0.025% crystal violet, and observed under a Leica microscope at ×200.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
